Indehiscent sporangia enable the accumulation of local fern diversity at the Qinghai-Tibetan Plateau.

BMC evolutionary biology - 28 Aug 2012

Abstract excerpt

BACKGROUND: Indehiscent sporangia are reported for only a few of derived leptosporangiate ferns. Their evolution has been likely caused by conditions in which promotion of self-fertilization is an evolutionary advantageous strategy such as the colonization of isolated regions and responds to stressful habitat conditions. The Lepisorus clathratus complex provides the opportunity to test this hypothesis because...
